Be it knownthat we, vVIInerAivrGEORGE` HANCOCK' and LEONARD T. STROMSWOLD, bothl citizens of the United States, and residents ofvMinot, in the county of Ward and State of North Dakota, have invented a new'and useful Improvement in Wagon and Truck Dumps, of which the following isa full, clear, and exact description.

Our invention relates to improvements inr Wagon and truck dumps, and itwconsists in the combinations, construct1o-ns, and arrangements herein described and claimed.

An object of our invention is to provide a wagon' and truck dump which is mounted` on a.A weighing scale, whereby the Wagoner truck' is automatically7 weighed when it is chance 4of slightly lifting the dump so as to lessen the weight of the truck upon the scales. y y

A-further object of Vour inventionis to providea device of the character described in which the tilting platform of the dump' is supported O11 each side thereof, thereby obviating a slight twisting or sagging of onel side with respect to the other. l n

A- furthervobject of our inventionlis to provide a device of the character described in which a guard is carried by the sivingable ortion of the dump, ed to closethe opening between` the raised end of the duA mp and the platform. f

A further object of our invention is to" provide a device of the character described which is relatively simple in construction, efficient for the purpose intended,`land which is not likely to easily get out ofr order. y

Other objects andadvan-tages will appear in thefollowing specification, andthe novely features of the invention will be particularly pointed out in the appendedl claims.

Our invention is panying drawings,

is obvious that the weighing means formsr no partof our invention except in so far as 1t cooperates with the parts about to be described. We have Lshown the platform 1: as being supportedby beams 2, which in turn rest upon a plank 3, ythe plank being carried bya lever 4 which is voperatively con` nected to a graduated bar or scale 5. The weight 'of the load `upon theframe 1 Will movel the yframe downwardlyy with respect to the .supporting pins 6, 7, and 8, whereby the load may be weighed by means of the weights 9 and 10. A platform 11 covers ,a

portion of the frame 1, and has a grain re` aboutthe hingesvl comprises an air cylinder 18 and a piston having a piston rod 19,

The cylinder by means of under side'of the supporting members 35.,` The platform ,'14 carries a bearing block QO'tokwhichy the rod 19 vis pivotally` secured. AnV air pipe 211, connecting with a` source; of supply `(not shown.) of the `cylinder '18, andis adaptedto convey the y compressedfair into the as to raise the rod 19,

cylinder `18l `soy which. in Vturn will swing the platform 14 about the hinges .15.'

close, the open end platform 14 are prevented from sagging 4with respect to=each other, since they are From this construction, it will be seen that when the rod 19 is move-d, it will swing the platform 14, which in turn will move the racks 22 with respect to the shaft 26.

Itpwill be noted, however, that the sides of theplatforni 14 are rigidly supported and cannot move with -respect to each other, since`v the racks and pinio-ns positively prevent thisinOvement. y

.The platform`14 is provided with a front y; wheel locking means` for the wagon or truck "whichis to be dumped. This means comprises a wheel locking board 28 which iSv hingedly secured to the platform 14 by means of hinges 29 and which forms a portion of the platform 14 when the latter isin closed or normal position. The board 28 is adapted Ito be swung about the hinges 29 when the platform 14 is swung upwardly so that the board 28 will always be inclined at the same angle with respect to a perpendicular line ydrawn through the hinge as the platform 14 makes with the same perpendicular.v The means for swingingthe board 28 about ythe hinges 29 comprises a '51 pair of racks 30 which are pivotally secured at a greater speed than is the rack 22.

to the board 28, and which are disposed between the rollers 23 and pinions 31. It will be noted that the pinions 31, carried by the shaft 26, are adapted to rotate with f the pinions 24. In other words, both of the pinions 24 and 81 are rotated as a unit when the platform 14 is swung upwardly. The pinion 24 is smaller than the piniony 31, so that the rack 30 will be moved iuiwardly rIhe greater movement imparted Ato thc rack 30 will swing the board 28 about the hinges 29 so as to normally keep the board inclined from the vertical at the same angle as the platform 14 is inclined from the vertical, but `in an opposite direction, In this manner, a trough or a V-shaped block is formed by the board 28 and the platform 14, and .prevents the wheels of the wagon or truck from moving downwardly along the platform 14.

, From the 'foregoing description of the various parts of the device, the operation thereof may be readily understood. Assume i that a wagon is drawn upon thegrain dump,

and thehorses arebroughtto.astop upon the supporting boardr 17. lVh'en thehorses are supported by the board 17, the '-front wheels of the wagon will be positioned above ,theboard 28. The wagon, with its contents,

may Vnow be weighed. After the wagon is...

weighed, it may be tilted so as to remove* the grain therefrom, and to convey it through the opening 12. To accomplish the raising of the platform 14, air is admitted into the cylinder 18, which will raise the rod 19, which in turn will swing Vthe platform 14 upwardly. The shaft 26 and the racks and pinions will automatically keep the board v28 inclined at the desired angle, whereby the front wheels of the wagon are preventedr from Amoving downwardly along the platform 14. The front end of the platform 14 carries a guard 32 which is hinged# ly secured thereto at 33, and which is guided at its lower end by channel irons 84. This guard closes-the opening made between the frame 14 and the frame 11 when the frame 14 is in raised position, and prevents the horses from backing'into thev opening 16. Afterthe contents of the wagon have been dumped, the' air may be exhausted from the cylinder 18 which will lower the platform 14 to its normal position, and will swing the board 28 into aplane parallel with the plane of the platform 14. The Vsame operation may be again repeated when it is desired to dump another wagon. In case a truck is desired to be dumped, it is brought upon the platforms 11 and 14 so that they front wheels thereof are disposed above the platform 28. The same operation is again repeated as heretofore described,and the truck is securely held from movement, when being dumped, by means of the board 28.

From the foregoing it will be observed that we have provided a simple and efficient device for automatically locking the wagon or truck against movement when the latterv is being dumped. If the cylinder 18 was mounted upon a support instead of being carried by the frame 1, air might be admitted thereto so as to slightly raise the platform 14 which would decrease the weight of the wagon recorded by the scale. We entirely obviate this chance for cheating by.

merely securing the cylinder 18 to the frame 1, so that if the rodyl9 wasl raised, it would not affect the Aweight recorded on the scale. The device jgsrelatively simple in operation, and is not likely to easily get out of order.

The boa-rd 28 in thel drawing, is shown inclined so as to make an acute angle with the plane of the frame 1. Itwill therefore be seen that the front wheels of the wagon or truck have a tendency to move toward the free endof the platform` 14 instead of in the opposite direction, thereby securely' holding the wagon in place.

We claim 1. A device ofthe type described co1npr1sing a frame having a swingable platform and a guard connected to the free endy of said platform, guidel members carried by said frame and being adapted to receive and to guide the free end of said guard,

said guard being adapted to extend between said swingable platform and said frame when said platform is in raised position.

2. In a device of the type described, a frame, a swingable platform, means for raising said platform, a transversely eX tending board hingedly secured to said platform and constituting a part of said platform, and means actuated by the movement of said vplatform for always' keeping said board' inclined so as to make the same angle with a vertical line through the hinge as does said swingable platform.

8. In a device of the type described, a frame, a platform hinged to said frame, means for raising said platform, a transversely extending rod rotatably carried by said frame, large and small pinions carried by said rod, racks pivotally carried by said platform and being in mesh with said small said platform, ybeingfhingedly secured to said platform, and a second set of rackspivotally carriedby said board and being in mesh with said largerpinions,` whereby said board is kept inclined so as to make the same angle with a vertical line through the hinge `asfdoes said swingable platform.

4. A wagon truck dump comprising a frame, a swinging platform carried by said frame, a board hinged to said platform and alined with the plane of the platform when the platform is in closed position, means for swinging said board with respect to said platform when said platform is swung into operative position whereby said board acts as a wheel stopfor the vehicle disposed on the platform. f
